The Siemens 3VA2116-5JQ32-0DA0 is a 3-pole SENTRON molded case circuit breaker rated for 160 A continuous current at 40 °C, with an ETU560 electronic trip unit configured for line protection. Its interrupting capacity reaches 187 kA at 240 V AC and 121 kA at both 415 V and 440 V — figures that put it squarely in high-fault-duty distribution, not just branch protection. At 500 V it still holds 79 kA, and at 690 V it drops to 4.25 kA, so the application voltage governs the SCCR you can claim on the panel label.
Current derating — the real continuous rating at your ambient
At 55 °C it derates to 154 A, at 60 °C to 148 A, at 65 °C to 142 A, and at 70 °C to 136 A.
Built-in undervoltage release and communication
This variant includes an undervoltage release (UVR) — design designation 3VA9608-0BB25 — and a communication function, so it can be integrated into a higher-level monitoring or shutdown scheme without adding an external relay. The overcurrent release is the ETU560, a programmable electronic trip unit that supports adjustable pickup and delay settings for selectivity coordination. There is no auxiliary contact version on this order code, so if you need a remote status signal, plan for an external auxiliary switch block.
